Observational Study
An elevated C-reactive protein level in an inpatient rehabilitation setting after joint replacement: To act or not to act? - that is the question.
C-reactive protein (CRP) is part of a battery of "routine bloods" performed by residents on patients when they are admitted into a rehabilitation unit. Generally, an elevated CRP is considered to be an indicator of an acute infective process. Numerous studies have indicated that the CRP peaks on the 2nd or 3rd day post total hip arthroplasty (THR) and total knee arthroplasty (TKR) and returns to normal by day 7. ⋯ These results suggest that even in uncomplicated elective joint arthroplasty, CRP's can remain elevated up to 14 days post-procedure, in the absence of an infective process. An isolated elevated CRP on admission to a rehabilitation setting should not be considered as an indicator of an infective process, but rather part of the normal post-operative inflammatory response. The elevated CRP should be monitored and only an upward trend requires further investigation and management.

Carbon dioxide pneumoperitoneum in laparoscopic surgery can bring about occult perioperative cerebral infarction, advancing our understanding of the causes of severe postoperative delayed recovery. ⋯ Our results emphasize the need for vigilance regarding adverse cardiovascular and neurological events caused by carbon dioxide gas embolisms when encountering the inadvertent situation of vessels rupturing. Timely monitoring of paradoxical gas embolism by transoesophageal echocardiography is necessary and can avert the risk of severe complications. Urgent consideration should be given to stopping pneumoperitoneum and switching to laparotomy for hemostasis so that the patient can obtain the best benefit-risk ratio.

Subgingival microbiome dynamic alteration associated with necrotizing periodontal disease: A case report.
Necrotizing periodontal diseases (NPDs) are a group of infectious diseases varying in severity, and microorganisms are responsible for these diseases. Currently, the oral microbiota in early disease has been poorly investigated; thus, the causative pathogen and dynamic alteration of the microbiome in NPDs remain unclear. ⋯ Changes in the subgingival microbiome can occurr before clinical symptoms appears, and Fusobacteria may be involved in the imbalance of the subgingival flora in the early stage of NPDs. Moreover, Neisseria is a potential bacterial candidate that deserves further study.

Observational Study
The prognostic value of the peripheral blood cell counts changes during induction chemotherapy in Chinese patients with adult acute myeloid leukemia.
To investigate the prognostic value of the circulating peripheral blood cell counts changes in acute myeloid leukemia (AML) at different time points during induction chemotherapy. We retrospectively analyzed the clinical and laboratory data of 237 newly diagnosed AML patients admitted to Fujian Medical University Union Hospital from January 2011 to December 2014.1. When primitive cells were first removed from the circulating peripheral blood, it was called peripheral blood blast clearance (PBBC). ⋯ Receiver operating characteristic(ROC) curve analysis showed the CR rate of patients with white blood cell count less than 1.25 × 109/L was significantly higher than that of patients with white blood cell count more than 1.25 × 10 9/L (P < .001) at day 5 of induction chemotherapy, but the RFS and OS was no significantly different (P > .05). The dynamics of peripheral blood blast in AML after initiation of induction chemotherapy, especially the time length to achieve PBBC, has important prognostic value for CR rate, RFS, and OS in AML patients. It is a simple and feasible method to evaluate the efficacy of AML.

Case Reports
18F-FDG PET/CT imaging for aggressive melanotic schwannoma of the L3 spinal root: A case report.
Melanotic schwannoma (MS) is an unusual variant of a nerve sheath neoplasm that accounts for less than 1% of all primary peripheral nerve sheath tumors. Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has unique value in detecting malignant MS lesions. To date, only 4 cases of MS with hepatic metastasis have been reported. Herein, we report the fifth case, which is the first reported patient with MS of Asian ethnicity with hepatic metastasis. ⋯ Unlike conventional schwannomas, which are completely benign, MS has an unpredictable prognosis. It is thought to have low malignant potential, and the malignant type tends to metastasize. FDG PET/CT has a unique and important value in the differential diagnosis of benign and malignant lesions, in detecting occult metastases, monitoring the treatment response, and assessing the prognosis of MS.
